Green Coffee Bean Extract: Blood Sugar & Cravings & Weight Loss

Diabetes affects about 11% of Americans 20 years of age or older and that number climbs to more than 26% with people over the age of 65 (with slightly more men than women affected by diabetes).  Pre-diabetes, however, affects 35% of people over 20 years and over 50% of people over 65, contributing to all sorts of chronic disease!

This week, scientists shared more evidence that green coffee beans can help control blood sugar and reduce weight related to type 2 diabetes. 
Chlorogenic acids are believed to be central. Some highlights from research by Joe Vinson, Ph.D.:

In a previous study, Vinson found that overweight or obese people who took such an extract lost about 10 percent of their body weight in 22 weeks. The new study sought to document the effects of various doses of a commercial green coffee extract on the blood sugar levels of 56 men and women with normal blood sugar levels. They got a glucose tolerance test to see how their bodies responded to the sugar. Then over a period of time, they took 100, 200, 300 or 400 milligrams (mg) of the extract in a capsule with water. Follow-up glucose tolerance tests showed how the green coffee extract affected their responses.
“All doses of green coffee extract produced a significant reduction in blood sugar relative to the original blank glucose challenge. The maximum blood glucose occurred at 30 minutes and was 24 percent lower than the original with the 400 mg of green coffee extract and the blood glucose at 120 minutes was 31 percent lower.”
Vinson's earlier work with green coffee bean extract has shown that without significant changes to diet, the body mass index for subjects shifted from preobesity to normal weight range. The study was small. Still, that's intriguing given the epidemic with obesity and diabetes. 

Detractors think this is all ridiculous because you can't eat the same diet and lose weight. However, green coffee bean extract seems to neutralize an enzyme (glucose-6-phosphatase) that promotes blood sugar surges after meals, basically the sugar swings that are not measured by fasting for 6-8 hours.

As a dietary supplement, it may be equally important for those of us with so-called "normal" blood sugar levels. That's because only fasting blood glucose levels over 125mg/dL (clear-cut cases of diabetes) concern most physicians. Fasting blood glucose levels between 100-125mg/dL are also  problematic and should be called out and treated as "pre-diabetic."

There's no getting around diet and lifestyle change but addressing blood sugar swings that lead to cravings is critical. Willpower is an expensive resource in the brain/body system, and with fatigue, hunger, and stress, willpower flags, leading to a desire for more sugar to fuel willpower (a vicious cycle when it comes to weight loss). The good news is that
 green coffee bean extract shows high bioavailability in humans and is widely available.

Having a little help from green java beans may be just the ticket. Write to me and let me know your own experience with green coffee bean extract!
